Even though Khalifa claimed he's taken part in a sign language rap battle before, this night was still unique. As Khalifa spit some raps, Kimmel introduced three "sign language interpreters" to take turns firing off his words in ASL. It turns out, one of those women -- Jo Rose -- is actually a deaf performer, not a sign language interpreter.

The entire event made for some pretty crazy dance moves and what must be the most unique rap battle anyone has seen in a while.

Have you ever seen anything like this?

UPDATE: A previous version of this story described Jo Rose as a sign-language interpreter. She is actually a deaf performer, despite what Kimmel said when announcing the performance.
